<div>hat cows make terrible managers!The cows, conveniently numbered 1&hellip;N1&hellip;N (1&le;N&le;100,000), organize t</div>
<div>he company as a tree, with cow 1 as the president (the root of the tree). Each cow except the presid</div>
<div>ent has a single manager (its &quot;parent&quot; in the tree). Each cow ii has a distinct proficiency rating,&nbsp;</div>
<div>p(i), which describes how good she is at her job. If cow ii is an ancestor (e.g., a manager of a man</div>
<div>ager of a manager) of cow jj, then we say jj is a subordinate of ii.</div>
<div></div>
<div>Unfortunately, the cows find that it is often the case that a manager has less proficiency than seve</div>
<div>ral of her subordinates, in which case the manager should consider promoting some of her subordinate</div>
<div>s. Your task is to help the cows figure out when this is happening. For each cow ii in the company,&nbsp;</div>
<div>please count the number of subordinates jj where p(j)&gt;p(i).</div>
